INTERNAL-COMBUSTION ENGINE.

application filed August Specification of Letters Patent.

Patented July 14:, 1914.

To all whom it may concern Be it known that I, \VARREN Donson GALE, a subject of the King of Great Britain, and a resident of \Vaterville, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Internal- Combustion Engines; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates" to improvements in internal combustion engines, as described in the present specification and illustrated in the-accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement 0 parts, whereby the inlet and exhaust ports are expeditiously opened and timed by a peculiar arrangement of valves and operating gear.

The objects of the invention are to eliminate as far as possible the delay frequently incident to the opening of a port, either for inlet or exhaust urposes, to construct a very simple engine cheap to manufacture and efiicient in its operation and generally to imrove in. this particular class o f engines.

In the drawings Figure 1 1s a vertical sectional view of the engine showing the valve in longitudinal section. Fig. 2 is a cross sectional view of the head and the valves. Fig. 3 is an end view of the valve gear. Fig. 4 is a vertical sectional view of the engine showing multiple cylinders.

Like numerals of reference indicate corresponding parts in each figure.

- Referring to the drawings, 1 are the cyl inders having the integral heads 2 and supported on the crank chamber casing 3 and surrounded by the water jackets 4, said heads having the valve chambers 5 and 6 extending clear through from the extremity of the head of the cylinder at one end to the extremity of the other end or in the case of a one cylinder engine just through the head, the circular bores forming said chambers 5 and 6 tapering from one end to the other.

7 are inlet ports to the cylinders 1 from the valve chamber 5.

head of the cylinder at the 8 are exhaust ports from the cylinders l to the valve chamber 6.

'9 are spark plug holes in the web of the heads 2 between the "alve chambers 5 and 6.

10 are pistons operating in the cylinders 1 and connected to the crank shaft 11 by the piston rods 12, said crank shaft 11 being journaled in the bearings 13 in the casing of the crank chamber 3.

14 is the valve gear chamber at one end of the cylinders 1 and formed of the plate 15, secured to the end of the engine by the bolts 16 and having the valve hole 17 adjacent to the upper end and the crank shaft hole 18 adjacent to the lower end,the outwardly extending flanged wall 20, secured to the plate 15 by the bolts 21 and gradually narrowing, said chamber 14 from the upper to the lower end, and the outer cover plate 22 secured to the outsidefiange of the wall 20 by the bolts 23.

19 is a stub shaft secured to the side of the crank casing just above the crank shaft bearing.

24 is a spur gear wheel journaled on the shaft 19 and having the hub 25 extending inwardly therefrom.

26 is a sprocket on the hub 25.

27 is a spur gear wheel fixedly mounted on the crank shaft 11 in the gear chamber 14 and coacting with the spur gear 24 therefore it will be seen that during the operation of the crank shaft 11, through its connection with the pistons 10, the spur gear 24 is rotated and consequently the sprocket wheel 26.

28 is a sprocket wheel fixedly mounted on the crank shaft 11.

29 is a tapered hollow rotary valve closed at its smaller end and suitably connected with the main inlet at its other and open wheel fixedly mounted 4 end.

30 are ports in the-wall of the valve 29 adapted to register with the inlet ports 7 31 is a thread formed on the valve 29 adjacent to the smaller end the open end of said valve being adapted to be connected to the explosive mixture supply.

32 is a sleeve valve encircling the valve 29 andhaving the ports 33 registering with the ports 30 and the ports 7,'said valve 32 being open at both ends and having the a thread 34 adjacent to its smaller end. The

I by the chain 'of the spur gear'24 through its connection with direction to the direction of rotation" of the valve-32 fits closely'in the valve chamber 5,

the walls of said chamber forming a bearin in the rotation of said valve. The inner wa of the sleeve valve 32 forms a bearing for the valve 29 and the smaller end of thelatter valve extends beyond the end of the said sleeve valve 32 into said valve gear chamber 14. a a 4 35 is a nut screwed on to the thread 34 against theend of thecylinder head.

'36 is a lock place.

37-is a sprocket wheel fixedly mounted on the sleeve valve. 32 at the smaller end thereof and connected to the sprobket wheel 26 38, therefore on the rotation the spur gear 27. of the crank shaft 11 the sleeve valve 32 isrotated 1n. one direction, that is to say, in an oppos1te crank shaft.

- pistons.

39 is anu't screwed on to the thread 31 against the end of the sleeve valve 32.

40 is a lock nut in place.' v

41 is a s rocket wheel fixedly mounted on thesma ler end of the valve 29 and connected to. the sprocket wheel 28 by the chain 42 therefore 11 and in an opposite direction to the sleeve valve 32 consequently it will be seen that in opposite directions insure a quick ful opening for the ingress of the explosive mixture. 43 is a similar valve to,.the' valve 29 and is encircled by'the sleeve valve 44 said valves being inserted in the valve .chamher 6 and secured exactly the same way as valves 29 and 32 the chains 38 and 42 passing over s rocket wheels mounted at the ends of said valves, said chains forming the connecting means'for operatin both the inlet-and exhaust valves, the va ves 43 and '44 being so set-to have their ports register with theexh'aust ports 8 in proper time according to the movements of the The valve gear chamber 14 is filled or I partially 'filled with 'oil so that the operatmg parts therein are well lubricated.

Further lubrication of the engine is not described herein as any well known system be used. the operation of this engine explosions are started as customary in internal combustion enginesand the rotation of the crank shaft brings the inlet orts 7 into register. with the ports30 an ,33 throu h v the sprocket and chain connections from t e nut holding the nut 35 in are larger than the ports securing said nut 39 the valve 29 is rotated, in the same direction as the crank shaft mg said auxiliary crankshaft to the valves 29 and 32, these valves turning in opposite directions the travel towardoperating in chambers 6 bring their ports Into alineinent with the exhaust ports 8 from cylinders through the va vs 43 out through the open the spent gases flowing end thereof.

' Simplicity of the parts of this engine just described constitute its chief merit while the operation thereof is .certain and quick for full clear openings at the inlets are assured as also are full clear openings at the outlets.

It will beseen that the orts in the valves rom the cylinders therefore proper timing may be assured.

' What I claim is In an internal combustion engine, in combination, a plurality ,of cylinders having across the heads thereof a-pair of circular valve casings extending continuously from one end cylinder to the other end cylinder and gradually diminishing in diameter from one. end to the other end, said casings having inlet and exhaust ports respectively to and from the cylinders, the said heads being recessed between havinga spark plug opening at the bottom of said recesses leading into each cylinder between said ports, oneof said casings at its larger end being connected to the inlet pipe and the other of said casings ,at its largerend being connected to the a set of tapered sleeves telescopica-lly arranged in each, of their casexhaust pipe,

ings and rotating in op specti'vely, the outer 0 said valves being open at both ends, and the inner of said valves being closed at the smaller end, each of said valves having external threads at the smaller ends, said smaller ends projecting beyond the cylinder, said valves having in st and exhaust ports adapted to meet in osite directions resald chambers and rotation and reglster, a nut and lock nut on each'of said outer sleeves at the smaller ends forming retaining members abutting the end walls of said casings, a nut and lock nut on each of said inner sleeves at the sprocket wh'eel fixedly mounted on the 'crank' s aft, a chain connecting said sprocket on .smaller ends thereof abutting the smaller the crank shaft with two of the aforesaid sprockets and auxiliary shaft. gears connectshaft and said crank shaft, a sprocket on saidauxiliary shaft,
